  rdf:value "Técnica de espectrometría de masas utilizada para analizar compuestos no volátiles como proteínas y macromoléculas. Supone la preparación de gotitas de moléculas del analito disueltas en un solvente y cargadas eléctricamente, que son introducidas en una cámara de vacío donde el solvente se evapora. Tal evaporación reduce el tamaño de la gotita, incrementando la repulsión coulombiana dentro de ella. A medida que las gotitas cargadas se vuelven más pequeñas, la carga excesiva dentro de ellas hace que se desintegren y liberen moléculas del analito. Las moléculas volatilizadas son analizadas posteriormente mediante una espectrometría de masas."@es, "A mass spectrometry technique used for analysis of nonvolatile compounds such as proteins and macromolecules. The technique involves preparing electrically charged droplets from analyte molecules dissolved in solvent. The electrically charged droplets enter a vacuum chamber where the solvent is evaporated. Evaporation of solvent reduces the droplet size, thereby increasing the coulombic repulsion within the droplet. As the charged droplets get smaller, the excess charge within them causes them to disintegrate and release analyte molecules. The volatilized analyte molecules are then analyzed by mass spectrometry."@en ;
